(2.38mH-9mH)

Features

The SDTR1103CAP Series of Surface Mount

ferrite wound inductor is the best solution

when high electrical and mechanical

performance is needed. Its length and

cross sectional area are optimized to

achieve the maximum sensitivity in the coil

axis. The construction of the coil offer high

mechanical performance due to the plastic

base and ferrite laminate.

High stability in temperature, ranges:

∆Ls/Ls (-40ºC

25ºC): -2% max.

∆Ls/Ls (+25ºC

+85ºC): +0.5% max.

Typical temperature coef cient ∆Ls/ºC:

+200±50ppm/ºC.

-40ºC to +125ºC for TPMS applications.

-40ºC to +85ºC for Keyless Entry Systems.

All dimensions in mm
